Isla Verde Passage (Verde Island Passages) is one of the busiest sea lanes in the Philippines. It is located between Batangas and Oriental Mindoro. Commercial and industrial ships pass through this passage to reach Manila from their port of origin in the south. They also use this sea lane to reach the southern part of the country from the Port of Manila.
Verde Island Passage is a popular domestic sea route connecting Batangas, Marinduque, Mindoro Occidental, Mindoro Oriental and Romblon.
The area has more than 300 species of corals, which is considered one of the largest concentrations of corals in the country or even in the whole world. Coral health is generally good, though the effects of global warming and increased pollution, may still lead to drop in diversity. The Verde Island passage is located next to Batangas Bay which is rapidly becoming a major refining and petrol chemical center in the Philippines. Until now, no infrastructure is in place to contain a major oil, or chemical spill.
